The answer to what inscribing an ellipse inside a rectangle has to do with your original question, is just that it's the simplest case that the "Draw Ellipse Inscribed in a Quadrilateral" tool should be able to deal with.

As you can see from the other posts in this thread, dxli has fixed the issues with the simple use of this tool and is now looking at more advanced mathematical cases.

dxli's revisions won't be available until the next release of LibreCAD.

So to solve your immediate problem I attach a DXF file IsometricCircles.dxf containing a left, right, and top view of an isometric circle of diameter 1 unit.

To get them into your own drawing, use file>import>block from the menu. Once imported, explode the block, then copy the circles to wherever you like in your drawing and scale them to whatever size you require.
